Ford C-MAX Solar Energi Concept is powered by a roof panel
The roof of the C-Max Solar Energi Concept uses: "a special solar concentrator lens" which will act like a magnifying glass to intensify the sun's rays before they hit the energy-converting panels. This should mean more energy harvested from the sun's rays for a faster, more-efficient charge. Who knows, it may even work in cloudy Blighty.
